Frederick Douglass' second autobiography, My Bondage and My Freedom, significantly revises key portions of his original 1845 Narrative and extends the story of his life to include his experiences as a traveling lecturer in the United States as well as England, Ireland, Scotland, and Wales. Douglass also frames his second autobiography differently, replacing the prefatory notes by white abolitionists William Lloyd Garrison and Wendell Phillips with an introduction by the prominent black abolitionist Dr. James M'Cune Smith. While the appendix to his first autobiography serves primarily as a clarification about Douglass' views on religion, the appendix to My Bondage and My Freedom includes a letter to a former master, Thomas Auld-a ship captain-and various excerpts from Douglass' abolitionist lectures. These prefaces and appendices provide the reader with a sense of the larger historical movement(s) in which Douglass plays an important part. Douglass later expanded and republished this autobiography twice more, in 1881 and 1892, both under the title Life and Times of Frederick Douglass.
